Parallel connection attains higher capacity by adding up the total ampere-hour (Ah). Some packs may consist of a combination of series and parallel connections. Laptop batteries commonly have four 3.6V Li-ion cells in series to achieve a nominal voltage 14.4V and two in parallel to boost the capacity from 2,400mAh to 4,800mAh.
Combining series and parallel options gives designers ways to meet voltage and current needs with common cell sizes. Using batteries in series boosts voltage; in parallel, it increases capacity. Series setups work well for big devices needing high voltages. Parallel fits for longer running needs.
Batteries A and B are in parallel. Batteries C and D are in parallel. The parallel combination A and B is in series with the parallel combination C and D. Again, the total battery pack voltage is 24 volts and that the total battery pack capacity is 40 amp-hours.
In most pack designs the cells are connected in parallel blocks (when P is greater than 1) and then in series. This is an important factor in managing the battery configuration. However, we will also discuss connecting series strings of cell in parallel as a separate article.
When designing a battery pack, cells can be connected in two ways: in series to increase voltage, or in parallel to increase capacity. Series connections add the voltages of individual cells, while the parallel connections increase the total capacity (ampere-hours, Ah) of the battery pack.
So, you would need 42 cells in total to create a battery pack with 24V and 20Ah using cells with 3.7V and 3.5Ah. 1. Why do I need to connect cells in series for voltage? Connecting cells in series increases the overall voltage of the battery pack by adding the voltage of each individual cell.
